ERS-2 (1995 - 2011) is the follow-up ESA mission of ERS-1. It was in 1989 when ESA decided to continue the ERS program beyond the lifetime of ERS-1. The ERS-2 satellite is essentially a copy of ERS-1, except that it includes a number of enhancements; it is also carrying a new payload instrument to measure the chemical composition of the atmosphere, named GOME (Global Ozone Monitoring Experiment). The mission ended on 5th September 2011, after the satellite's average altitude had already been lowered from 785 km to about 573 km. At this height, the risk of collision with other satellites or space debris is greatly reduced.
